I recently purchased the halo stack. i was doing my maiden flight and the drone just fell to the ground. upon further inspection i noticed that i was not getting communication from the ESC. When i plug in lipo i get no beeps so i figured the esc was fried so i ordered a new one. New one came in today and when i had everything complete i plugged in lipo and still no beeps. Figured it was my Halo FC so i found an old esc that i had and hooked it up to halo fc and i got all the beeps from the old esc. no matter what i've tried i can not get the halo esc to work and its brand new. any suggestions would be greatly appreciated.
